What to expect
PRP (platelet-rich plasma) uses your own blood components, so reactions are usually mild: redness, slight swelling, tenderness, and sometimes minor bruising at injection or microneedling sites for 24–72 hours.
For scalp or facial PRP, a little pinkness and sensitivity in the first day or two is normal.
The first 24 hours
Follow your clinic's protocol, but commonly: avoid washing or applying products to the treated area, skip makeup, and don't sweat heavily for the first 24 hours so the area can settle.
Be gentle — no scrubbing, no pressure, no harsh actives.
What to avoid for 24–72 hours
Avoid alcohol, sun and heat (sauna, hot yoga), strenuous exercise, and — unless your clinician says otherwise — anti-inflammatory painkillers, which can blunt the PRP healing response.
These precautions protect the very mechanism PRP relies on.
The recovery timeline
Visible redness fades within a few days. The actual benefits — skin quality, hair density, tissue repair — build gradually over weeks to a few months as collagen and healing responses develop.
PRP is a course-and-patience treatment, not an instant result.
Normal vs warning signs
Normal: redness, mild swelling, tenderness, and minor bruising that improve over a few days.
Warning signs: severe or spreading swelling, increasing pain, pus, or fever — possible infection that needs the clinic's attention.
